The two service techs that replaced my a/c unit were very nice and quick. Replacing the entire unit was a huge task, especially in 110+ degrees. They worked non-stop to get the job done. Before leaving, they took the time to explain how the system worked and answered all my questions. The price was great, and I couldn't ask for better service. Job well done Air Force Heating & A/C!! I would highly recommend this company and will use them in the future.
